PJM Interconnection LLC, the largest US electric grid, has failed third straight time to secure enough future supply commitments, highlighting the scale of the challenge posed by the AI boom.

A PJM market watchdog calls the shift a "massive wealth transfer" to tech companies, but there's a peak-demand loophole.

PJM's capacity auction for 2027/2028 fell 6,517 MW short, hitting the $333.44/MW-day price cap as AI data center demand outpaces grid supply additions.
